Format for CRZ PERF tables

Columns delimited with ;

First column is altitude

Second column is FF per engine in kg/hr

  • Column contains values for weights ranging from 140t to 290t in 10t increments
  • Delimited with ,

Third column is IAS

  • If single value, apply to all weights
  • If multiple values, apply to respective weights (delimited with ,)

Fourth column is MACH

  • If single value, apply to all weights
  • If multiple values, apply to respective weights (delimited with ,)

Format for ECON tables

2d matrix of mach values

Columns delimited with ,
One file per altitude and MMO combination

First index is weight (equates to the lines in the file)

  • Must be of 140, 150, 160, 170, 180, 190, 200, 210, 220, 230, 240, 250, 260, 270, 280, or 290

Second index is CI (equates to the columns in a line)

  • Must be in range [0, 999]

Format for raw curve tables

2d matrix of curve parameters

Columns delimited with ;
Parameters delimited with ,, ordered a, b, c

First index is altitude (equates to lines in the file)

  • Must be of 250, 270, 290, 310, 330, 350, 370, 390, 410, or 430

Second index is weight (equates to the columns in a line)

  • Must be of 140, 150, 160, 170, 180, 190, 200, 210, 220, 230, 240, 250, 260, 270, 280, or 290

Usage of function


  f(x) = a \cdot \sqrt x + b \cdot x + c

Extract parameters a,b,c from the table
x is the CI and must be in range [0,999]
f(x) is the mach number for the given altitude, weight, CI, and MMO

Conversion of weight to index

f(x) = \frac{x - 140}{10}

x is weight (see range restrictions where applicable)
f(x) is the resulting index for the LUTs

Conversion of altitude to index

f(x) = \frac{x - 250}{20}

x is altitude (see range restrictions where applicable)
f(x) is the resulting index for the LUTs
